So society changes to accommodate ops plan
Everyone has an income of £250k per year.
20 years down the line, all is well.
Neighbour A is fairly thrifty. In that time they have saved £20,000,000, and lives in a house worth £500,000.
Neighbour B lives to live well, but isn't careless. They have saved £1,000,000 and own a house and furnishings worth the same amount of money.
Neighbour C likes to really enjoy life. Their house is worth £10,000,000 and they haven't saved anything, spending on holidays, first class travel, champagne, fancy cars and, of course, their beautiful house which is furnished with the best of everything.
Then disaster strikes. An earthquake hits, and all their houses and belongings are completely destroyed. Thankfully nobody was home at the time, and they all survive.
Is neighbour A immoral? And who should pick up the pieces for neighbour C, considering they all have had the same?
